To all 101720711. it may concern.'

lie it known that Finnair M. (.''oLnsn'rrn7 a citizen ot' the United States ot America. and resident ot Cincinnati, in the county of Hamilton and State of Ohio, have invented a neiv and useful improvement in inserts tor Plastic Materials, oi vvhich the 'lollovvino' a specification.

in object oi' my invention is to provide an `insert for plastic construction. that easily applied, crieaply manutactured and that ivill be highly eficient.

Another object oi" my invention is to 1 vide a device tor the purpose stated, that can be readily assembled.

Another object is to provide a device ivhich atteihaving' been partly embedded in the plastic, can have its projecting par' readily bent to anydesired position.

Another object is to eliminate any unsightly projections from the plastic after the mold has been removed therefrom.

These and other objects are attained by means described herein and disclosed in the accompanying` drawing' in which:

Figure l isla perspective vieu' ot a device embodying' my invention mounted upon a mold used in plastic construction 1Work.

Fig'. is a side elevation ot the device shovvu in Fig. l, part in section, partly embedded in the plastic.'

Fig. 3 is a perspective vieiv ot a device embodyingmy invention partly embedded in the plastic.

My invention comprises a cap A through which extends an insert B. The perforated cap A is pressed into a` form similar to an inverted tray and has the sides (t extending' from its center or raised portions o. thev edges ot the sides forming a base a3. The insert B has an eye o adapted to be secured between the under side (it of the cap and the mold C and has fingers o extending through thepertorations (i5 in the center portion ot the cap. recess a is formed in the under side ot the cap raising' the boss o7 upon the cap. The eye?) termed on the insert ei:- tends partly over this recess. A nail D. a. series ot sharp projecting' points E formed on the base or any other means may be used to secure the cap to the mold. That part ot the insert extending into the mold may have any shape or form that Will unen en'ibedded in the plastic and when' the mold has been removed. support the eye for ied on the insert. .f'i iter the mold C is removed fromV Specification ci' Letter.; Tatent.

the plastic the eye 7) is readily moved aivav by inserting; a chisel into the recess afi ot' the cap, since nthe recess 0,6 attords room tor the insertion of the tool betvreeii the eye and the cap. The insert may be oi' any shape or torni.

The cap may be made iu any shape but is pre'lkuably made so as to have a shallow tray-like form. the depth thereof being subtantially equal to the thickness of the ma- .rial ot which the insert B is made.

The application vice is as follows:

The `fingers 7) ot the insert are passed through the perforations in the cap and eX- tend beyond the upper surface or" the cap, thereby seating' the eye upon the under side or". the cap as shown in Fig'. E2. The cap is then secured to the mold or temporary flooring' C by means of the nail l). The plast-ic is then placed on the mold and surrounds the fingers of tha insert. The cap prevents the plastic engaging the eye (Z. ,Vhen the mold or tennliorary l'looring` is removed the fingers ivill be securely embedded in the plastic the cap will be on the surface of the plastic. and the eye can then be readily bent aivay from the cap by inserting a chisel or similar tool` between the eye and the cap. Lat-h or anything that is to be supported by the plastic or suspended therefrom can be readily attached to the eyes.

lhat claim is:

l. fis a nevv article ot manufacture for use vvith plastic construction, a cap conn prising` a i'lat metallic plate having substantially the shape of a shalloiv inverted tray and having' spaced periorations in its top, fastening' means adapted to be driven into the mold and to thereby secure the cap in position. and an insert comprising` a single metallic rod having' an eye formed intermediate its ends and having its ends turned upon themselves to form hoolrs, and each. end extending' through one oit the perforations in the p ate. the eye assuming a position Within th Y, depressed portion of the cap and being' capable of being` moved to an extended position attcr the hooked ends are embedded in a plastic material..

2. As a nenv article of manufacture for 'use ivith plastic construction, a cap comi'n'isinp; a dat metallic plate having' substantially the shape oi? a shallow inverted tray and having' a re vess and spaced perforations iu its top. and an insert comprising` a mctaland operation ot my delic rod-having an eye formed intermediate its ends and having it-s ends turned uponA themselves and each end extending through one of the pertorations in the plate, the eye assuminga position within the 'depressed portion ot the cap and extending` over the recess and being capable of being` movedto an extended position after the ends of the rod are embedded in a plastic material. f

3. As a new article oi manufacture for use with plastic construction, a perforated cap, a recess formed on thc cap, an insert, an eye formed on the insert, the eye being 'WiLLiAM M. eoLnsMrrr.
